Network operator ESB has reported multiple faults across the Irish Republic, with counties Cork, Kerry and Donegal among the worst hit.

Northern Ireland Electricity Networks said 1,000 customers had been left without power, while Electricity North West said four weather-related faults had led to problems for 419 customers in Cumbria and Lancashire.

Western Power Distribution said more than 950 homes had been left without electricity in south-west England and nearly 100 were without power in south Wales.

There was also bad news for commuters in south Wales, with Arriva cancelling a number of train services for the morning due to the high winds and heavy rain.

Traffic Scotland said the Forth Road Bridge had been closed in both directions at about 9am, and tweeted it would be re-opened in 15 minutes. But there had been no confirmation was open again by 10.30am.

There have also been reports across the country of fallen trees and roads being blocked.

And while Windsor, the scene of Friday's royal wedding, looks set to escape the worst of the storm, those charged with carrying any train on Princess Eugenie's dress may have a challenge on their hands, Ms Kent added.

Guests arriving at the royal wedding of Princess Eugenie and fiance Jack Brooksbank in Windsor were also buffeted by high winds, with some hats blown off and many having to hold them.

"It's going to be blowy but not enough to cause any weather impacts," she said.

"The people trying to hold the train are going to have to be doing a good job if she's got a long one because the breeze will be catching it."

The happy couple are likely to enjoy a dry but cloudy day, with the potential for brighter spells in the afternoon.
